Biomarker discovery points to blood test for osteoarthritis

By - March 22, 2015 1 Picture
While blood tests are used to rule out other forms of arthritis, the diagnosis of osteoarthritis (OA) generally relies on physical symptoms, with X-rays or MRI scans used for conformation if required. But researchers at the University of Warwick in the UK have identified a biomarker for OA that could lead to a blood test that could diagnose it, and rheumatoid arthritis (RA), years before physical symptoms present themselves.

Smart bandage detects bedsores before they appear

By - March 18, 2015 2 Pictures
Bedsores are more than a pain in the backside for bedridden folk, they can develop into dangerous infections and heighten the chances of a patient dying. While swollen ulcers on the skin are a pretty sure sign of their presence, by this point it is often too late for some of their effects to be reversed. But a team of researchers have developed what could function as an early warning system, a smart bandage containing flexible electronics that detects tissue damage before it becomes visible on the surface of the skin.

Researchers identify how cells get their orders to heal wounds

By - March 18, 2015 2 Pictures
When you cut on your finger or scrape your knee, cells rush to the wound and repair or replace the damaged tissue. But how exactly this works – in particular how certain cells become "leaders" in the process – has long been a mystery. Now researchers at the University of Arizona (UA) have identified the mechanisms that cause and regulate this collective cell migration. Armed with this knowledge, biomedical engineers will be able to design new tissue regeneration treatments for diabetes and heart disease as well as for slowing or stopping the spread of cancer.

Non-invasive Alzheimer's treatment restores memory using ultrasound

By - March 11, 2015 1 Picture
Alzheimer's disease is a chronic neurodegenerative disease that most often begins in people over 65 years of age. Usually it starts slowly and continues to worsen over time until the sufferer succumbs to an increasing loss of memory, bodily functions and, eventually, death. Research has shown that there is an association with Alzheimer's and the accumulation of plaques that affect the neuronal connections in the brain. Now researchers at the University of Queensland have discovered a new way to remove these toxic plaques using a non-invasive form of ultrasound therapy. Read More

Heart-on-a-chip beats a steady rhythm

By - March 11, 2015 1 Picture
The growing number of biological structures being grown on chips in various laboratories around the world is rapidly replicating the entire gamut of major human organs. Now one of the most important of all – a viable functioning heart – has been added to that list by researchers at the University of California at Berkeley (UC Berkeley) who have taken adult stem cells and grown a lattice of pulsing human heart tissue on a silicon device.

Prosthetic arm takes alternate route to mind control

By - March 9, 2015 3 Pictures
Researchers from the Medical University of Vienna have developed a technique that allows amputees to control a robotic prosthesis with their mind when there's no neural connection left to exploit between the brain and the part of the hand that remains. Called "bionic reconstruction," the procedure was applied to three patients who were able to successfully use the prosthesis to undertake routine activities, thereby improving their quality of life.
